Render image and mesurements?
Blender 2.8 comes with a plugin pre-installed called MeasureIt. This allows adding Measurement notations as scene data.  You can then render the annotations separately and composite them back in. In order to get your measurements rendered, all you would have to do is:

Click on the Render button in the Render panel which is going to render your measurements as a separate image based on the active camera
Open up a new Compositor window or just switch the workspace to Compositing, add an Image as well as an Alpha Over node
Set the image for Image node to generated image by the MeasureIt add-on
Plug your rendering into the upper socket and the generated image into the background (lower) socket of the Alpha Over node


Note: MeasureIt is a large and complicated tool, some research is required. I'd suggest have a look into the manual: https://docs.blender.org/manual/en/latest/addons/3d_view/measureit.html or watch some time consuming youtube tutorials.
